Alternative to "Decimator"?

in Daz Studio Discussion

Hello! Is there an alternative to the Decimator plugin in order to reduce the poly count?

By the way, I got the Alembic-exporter.

    Not in DAZ studio keeping rigging

    for other applications I use the poly reduce in Ultimate Unwrap 3D

    This 100%. I use poly reduce in Ultimate Unwrap 3D as well, but you will need to re-rig the mesh. While the limbs can work just fine with using the transfer utilty with the original figure, the face rig will be busted. Depending on your use, that might be fine.

    With UUW3D You don't get to pick weights like Decimator, but you get to reduce verts, which may be important for your target.

    Decimation master in zbrush is amazing. But as others point out, it's only helpful if you don't need the daz studio rigging.

    Does the iClone 6 stuffe reduce the polys when it importas a Genesis 2 figure?

  • WendyLuvsCatzWendyLuvsCatz Posts: 38,513

    No

    it it for iClone btw I mostly use UUW3D after re-exporting animated figures to create low poly crowd props

    i get genesis 1&2 and other DAZ figures dressed under 5K polys fully animated I can use alt and transform to duplicate and merge use collect clip and make large animated crowds.

    And what about the Decimetor plugin itself? Does it help a lot?

    Decimator has its uses esp within DAZ itself where it is the only way to keep rigging

    Since the verts are the 'anchor points' of the polys you cannot reduce polys without also reducing the verts.  Decimators almost always triangulates the mesh and usually ruins topology and symmetry, thats why they are called decimators.

    It has to reduce verts, the question is does it retain a 'control cage' of the original mesh and verts so morphs can be projected on to the reduced mesh.

    bought, installed, tested.

    The FBX dialog box shows the vert count matches, but the poly count is different. Hexagon also shows the same results. (but you can delete unused verts from the OBJ, and the FBX dialog is WRONT)

    @jestmart take a look at the attachments.

    I like that you can choose between targeting Verts or Polys with UUW3D, (and as jestmart says it works the traditional way of lowering both). But UUW3D don't keep daz rigging and has no weighting system.

    The Daz decimator has a weighting system to selectively reduce polys for different groups more or less. But quick testing with dress shows that UUW3D holds up better for certain garments.

    Simply not possible and I don't trust what Hexagon say.  Not going to buy it just to check with Blender though.

    you think the FBX dialog is a lie? UPDATE: It is.

    You mean I have to install blender again!? OK FINE! For Science. I went this far.

    So I am getting closer. If you export OBJ, you can remove unused verts. However then you have no rigging and at that point UUW3D is better for me.

    OK, the FBX dialog is a lie. If you go ahead and export, then reimport the FBX into daz, the poly and vert counts both go down. Which is good to know! So the Daz tools just aren't looking at the right thing :( But now I can tinker with decimator :)

    OK, so my new path is this. I use UU3WD for clothes. Because It keeps the shape much better than decimator (at pretty extreme reduction rates 75% or so). I don't mind using transfer utility to re-rig clothes. I'd rather them look pretty.

    However for people, I'd much rather use Daz Decimator. Because I don't want to lose the rigging for people...and they look good enough. Though, thinking about it, I typically hide verts I don't have shown on the character (via geometry editor tool) and not really need decimator, but I think it will have some uses nonetheless.

    So I will use both :)

    So with UU3WD I lose all rigging?

  • WendyLuvsCatzWendyLuvsCatz Posts: 38,513

    not from an fbx

    but no good for Daz/Poser rigging

    Are there other programs suitable to reduce the polygon numbers of a DAZ3D model in FBX format? Later on I want to send them to iClone, but I don't want the rigging to be get weird.

     

    3D-Coat?

    I meant it is no good for rigging to be used in DAZ or Poser.

    on an FBX export it is fine.
